MANGABEYS. The Mangabeys, or White-Eyed Monkeys, as 

 they are also called, acquired the first name mentioned because the 

 great French naturalist, Buffon, was of opinion that they came from 

 the Manongabe or Mangabe district of Madagascar, whereas, as a 

 matter of fact, they consist of a small group of West African species. 

 They are represented in the illustrations by Hamlyn's Mangabey 

 (Fig. 128) and Jamrach's Mangabey (Fig. 129). They are closely 

 related to the Guenons, but are separated from that large group of 

 Monkeys by reason of the structure of the teeth, which resemble 

 the Macaques in this respect. Beyond this, the prominent white 

 eyelids at once serve to distinguish them, as well as the oval-shaped 

 head, long muzzle, and hairs not ringed with various colours as in 

 the Guenons. 



Other species that may be mentioned in addition to the two 

 already referred to are the Sooty Mangabey, which is deep, dull 

 black in colour, with the chin and under-parts ashy, the face being 

 livid and blotched with dark-brown. The hair on the top of the 

 head is not carried in the form of a crest. The White-Collared 

 Mangabey is blackish-grey, with a white collar round the neck, and 

 the same colour on the cheeks, throat and chest. The White- 

 Crowned Mangabey derives its name from a white-spotted crown, 

 and also has a streak of white along the centre of the back, whilst the 

 Grey-Cheeked Mangabey is at once identified from its relatives by 

 having the hair on the crown elongated into a crest. It is blackish 

 for the most part, acquiring its name from the greyish colour of the 

 throat-sides and cheeks. Thus we see that the four species last 

 mentioned have all been accorded English names because of the 

 colour of, or markings upon, the body, whilst the two remaining 

 species (Figs. 128 and 129) have been named after the well-known 

 animal dealers, Messrs. Hamlyn and Jamrach. Both these species 

 are interesting because they are recently discovered Monkeys. Both 

 kinds are white, and Hamlyn's Mangabey has a curious freckled 

 face. The two appear to be doing well at the London Zoo, and share 

 the same cage. Hamlyn's Mangabey came from the Upper Congo, 

 and Jamrach's Mangabey from Central Africa. All these Monkeys 

 are of arboreal habits, living in troops in the forest, and feeding 

 chiefly upon various fruits. They appear to be of active disposition, 

 and in captivity become docile and entertaining. 



JAPANESE MACAQUE. This species (Fig. 130) introduces us to 

 the Macaque Monkeys, which are Asiatic species. They are more
